Be 1t known that I, rI'mwN-nracig a citizen of the United States, and aresident' of Minneapolis, Hennepin county, Minne- Sota, have inventedcertain new and useful Improvements in Incinerators, of which thefollowing is a specification. i

The object of my invention is to provide an apparatus in which refuseand garbage may be placed and consumed.

A further object is to provide an improved form of'garbage grate, whichwill allo'w the flames to pass in and around the mass of garbage,thereby efectually drying 4same and hastening the consumption.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in'various constructions andcombinations, all as hereinafter described and pointed out in theclaims.

In the accompanying drawings forming part of this specification,` Figure1 is a vertical, sectional view-through an incineratorembodying myinvention, Fig. 2 is a` similar view, taken on a section line at rightangles substantially to the section line of Fig. 1.

In the drawing,"2 represents the wall of the incinerator, having a waterleg or circulating chamber 3 extending around and the combustion chamberet. This chamber has a flue 5 leading to the stack and a pipe 6 in thetop through which refuse from an upper floor maybe discharged into thecombustion chamber. An opening 7 is provided in the front wall of thechamber, having a charging door 8. Beneath this charging door is atiring door9 adjacent to the fuel grate 10 supported on brackets 11 inthe lower part of the combustion chamber above the ash pit 12. This ashpit has the. usual door 13 leading thereto. I

Near the rear wall of the combustion chamber and a suitable distanceabove the fuel grate 10 is a header 14. preferably of extra heavymaterial and' connected at each end Vith the circulating chamber 3 inthe side walls .of the combustion chamber. A series of Astay ,tubes 15lead from this header outwardly to the front wall of the combus tionchamber communicating with 'thecir- Specification of Letters Patent.Application mea septembei '27, 1913. serial No. 792,117. l

' thrown. Theyl are inclined downwardly and inwardly from ,the front.wall of the combustion chamber to the header and the material depositedon these tubes has atendency to slide inwardly toward the header. Aseries of similar tubes 1,6 leadfrom the top of the header andcommunicate with the circulating chamber in the top of the combustioncham-v ber. These tubes 16 are spaced from the rear wallof-thecombustion ehai'nber--so that the flames from the burning fuel onthe grate l0 may passup between these tubes and the wall of thecombustion cham ber and circulate in and around the mass of refuse orgarbage supported by the tubes 15 and the header 1st. l have found thatthis arrangement will insure ja more complete combustion of the garbagethan where it is allowed to'lie in direct contact with the outside wallsof theA combustion chamber.

Furthermore, a large area of the circulating tubesis exposed to theflames of the burning In ,various ways the details of construcl tionherein' shown and described mame modified and still 'be within the scopeof my invention.

I claim as mty-invention 1. 'An incinerator comprising a combus-4 tionchamber having water circulating chambers 1n its walls and :a fuel gratein the lower part ci' said chamber, a header arranged horizontaliy nearthe' rear wall of said combustion chamber. above said grateandcommunicating with said; buter ,circulating chamber, circulatingA tubesextei'rd'ing vertically from'said header to the water cir culatingchamber the'rvtop of said combustion chamber, and similia-rtnbesextending forwardlgand upwardly from said headerf' to the frontWall of saidcon'ibustion chamberend also communicating with" said watercirculating chamber.

incierator comprising walls hav-` ing-waterfcircula-ting chamberstherein; and

'a combustion chamber provided witha -f-uel grate, a header extendingtransversely of vsaid combustion chamber 'above said' fuel grate andnear the' rear wall of said'conibustion chamber, and circulating tubesleading from said header and communicating with said Water circulatingchambers inthe front wall -of said combustion chamber, said tubesforming an inwardly and downwardly inclined drying grate, andV the frontwall of said combustion chamber having a filling opening above saiddrying grate.

` 3Q An incinerator comprising a combustion chamber havingWater-circulating chambers in I its Walls and a fuel grate in the lowerpart of said chamber, a comparatively large header pipe extendingtransversely of said combustion chamber near the rear Wall thereofl andadjacent to said fuel grate and having its ends connected to saidcirculating chambers, a series of circulating pipes extending upwardlyfrom said header p ipe and communicating with said circulating chambersin the top oi said incinerator, a series of circulating tubes extendingupwardly from said header pipe'to the circulating chamber in the top ofsaid incinera-A tor, a series'of similar'tubesextending from Y saidheader .pipe upwardly and' fqrwardly to the circulating chamberintherfront Wall of said incineration said incinerat'onhaving a fillingopening above and near the outer portion of said last named tubes, and afuel supply door vbeneath said tubes.
